Abstract
In this study, textile finishing wastewater was treated with Fenton's reagent (hydrogen peroxide-ferrous iron system). Under unstable and complex wastewater condition, Fenton's reagent was unable to comply with the standard set by the authority with respectto COD. However, removal of SS complieswith . the standard while visibility of the wastewater improves by more than 50 %. Removal was mainly by DB radical oxidation as compared to hydroxide precipitation. . Mineralisation of more than 50 % organics was observed after 5 min.utes reaction while 77 % mineralisation was observed aft.er 30 minutes reaction. The amount of hydrogen peroxide and ferrous iron substantially affects the quality of the treated wastewater.
